It is an object of our invention to provide an improved casting plant ofthe type wherein a moving table carries the molds pastthe point at whichthe metal is poured.

t is also an object of our-invention to provide an improved travelingtable for car rying the molds past the pouring point and to provide asuitable driving means for a table of the type described. l

With these and other objects in'view our invention comprises a circulartraveling table or turntable 1 enclosing an area in which are placed thedrag molding machine 2, roll-over machine 3 and the cope molding machine4. These machines are positioned so as to be supplied with sand from anoverhead sand bin carried upon the foundations 5. OVVithin the areaenclosed by the table there are also mounted a cope jolting machine 6and a drag jolting machine 7, both machines being mounted so that thesand from the copes and drags will fall into a sand pit 8 formed beneaththe jolting machines 6 and 7. The pit 8 extends beyond the travelingtable 1 and mounted above this portion ot the pit 8 is a Wheel joltingmachine 9. Between the jolting machine 7 and the molding machine 2 thereare provided a plurality of gravity conveyors 10 thatprovide storagespace for the drags while cooling and are served by traveling hoists onan overhead monorail 11 at one end and on an overhead monorail 12 at theother end While between the jolting machine 6 and molding machine 4there are a plurality of 55 tracks 13 joined by transfer tracks 14 thatprovide a means for moving the buggies on which" the -copes -and chills'are carried. Leading 'fromonef track 13 is a `transfer grthe-loaded'bu'ggies tothe storage tracks 16".5VV The monorail"12 connectswith a monorail 17 thateXtends above the center line of track :15thatprovides ameans for convey' G0 the table for more than half'thecircumfer- 65 ence of' the table and is provided with a spur orextension 18 :which goes to the rollover machine ,3; spurs`19, 20, and21 which join fsoas to form complete loops serving the molding -*machine4; a spur 28 extend` 70 ing without'tlie'table area; and spurs 22, 23,24 and .25 which 'join forming loops for the routingof a pouring ladlefrom a' ladle hoist 26 in `ront of the bull ladle 27 to a pouringposition over the traveling table 1 7 5 and back tothe ladle hoist 26.

In .the operation of the plant, a drag is taken from the conveyorlO and'placed on the molding machine 2 by means of a hoist on the monorail 12.When'filled with sand, 80

the dragis turned over on the roll-over machine then picked up by meansof a hoist on the monorail 18 and placed onvthe traveling tablel1, thecores -being placed after the drag is placed on the table. A cope and 85chill, secured together in any desired way, are brought from a storagetrack 16 and lifted from the buggy onto the molding machine 4 by meansot a hoist on the monorail 21. Whenilled with sand, the cope and chillare lifted from the molding machine 4 by means of a hoist on themonorail 19, turned over while supported from the monorail, the chapletsplaced and the chill oiled and then moved along on monorail 17 and 95lowered down and clamped in position-on a drag'that is being carried tothe pouring position on the table 1.

The ladles, filled from the bull ladle 27 are raised by the ladleelevator 26 so as to be engaged and conveyed at a fixed height, by meansof a traveling support on monorail 25, to a pouring position on monorail17. The height of the ladle when supported from the monorail 17 is fixedso as to insure the 105 pouring of all molds with the ladle at theproper distance above the molds and the lengthbf the monorail 17.permits of the pouring being at such a point that fthe'ca'sting Will beat the proper temperature for removal from the mold When the movement ofthe'table 1 brings the mold beneath'the monorail29.- With the mold inposition 'beneath the monorail 29, the cope and chill are removed bymeans of a hoist on the mono:l

rail 29 and placed on the joltin'g"inachiiie',`

the casting is cleaned byel power/driven,

brush supported from the crane 30and then placed by the crane 31 upon agravity conveyor 32 upon which it travels to thesoaking pits. Ahub corereamer 33 removesrthecore A.. from the hub Whilethe casting. rests upontheV conveyor 32. The drag is removed fromthe.

@able 1 to a jolting `machine ZI-from Which it is'removed, by means of ahoist on'fthe monorail 3 4, to the gravity conveyors 10,*Where it coolsas it moves toward themonorail 12,

Where itis again picked up for furtherjuse.

The sand deposited in thepit 8 is conveyed by means of belt conveyors,and an elevator 75 to a main storage bin carried on thev foundations 76froml which it is conveyed by other conveyors and elevators to thesupply' bin carried on the foundations 5, the sand being tempered andconditioned while being moved. Foundations 7 7 and 78 carry partof theoverheadstructure of the elevators and conveyors-but as the sandconveying apparatus forms no part of our invention 1t 1s not shown indetail.

The traveling table 1 comprises spaced circular channel members 35 and36 connected at regular intervals by girder members 37 that are securedto the channel members 35 and 36 by angles 38 and gusset plates 39,additional reenforcing members 40, and a top consisting of a pluralityof metal sections 41 bolted to the channel members 35 and 36. Secured tothe undersides of the girder members 37 are supporting rails 42 thattravel on Wheels 43 journaled on axles 44. The axles 44 are supported inbearings 45 mounted on bearing bases 46 on a suitable foundation 47 thatis in the form of a pit so as to bring the table top at the properheight above the floor level. To the undersides of the girder members37, and between the supporting rails 42 is a member 48, substantiallyH-shape in cross-section, that has one leg formed into a rack 49 engagedby a drive pinion 50 and the other leg forming a guide 51l that engagesguide rollers 52 carried by roller bases 53 secured on the bearings 45,the legs being 1,605,442 BEST AyAll-ABLE provided with flanges by whichthe member 48, is secured to the girder members 37. Blates 54, supported4'ateach sidefof the pit by angles 55 secured to the foundation by bolts56, are connected by angles 57 and serve to keep the pit'clear.' Securedto the outer faces of the channel members 35 and 36 areA platesv 58which -projectbelow the channel members 35 and 36 and overlap the Vupperedges of the plates 54 and keep material from droppingfrom the tableinto the pit.

To operate the table there are provided a plurality of driving 'units 59which are placed in a pit beneath the controland pouring platform 60.vThese units are identical except that they are designed to operate thetable at different rates of speed. The units are, therefore, adapted .toserve as spare or emergency units foreach -other and, with the range forthe pouring and opening points given by the monorails 17 and 29theyprovide means for moving'the molds from pouring point to Vopening pointin the proper time forA castings differing greatly in Weight. Each unit59 comprises an electric motor 61 'controlled 4from a :controller box 62on the platform 60Fand connected by a coupling 63 to shaft'64l of aWeighted y-Wheel or kinetic energy device 65, the shaft 64beingconnected at its opposite endto the sha-ft'of a spur gear speedtransformer 66. The shaft of the spur gear speedtransformer 66 isconnected through a reversin -clutch 67 controlled by a lever 68 from te control platform 60. The Vclutch* 67 operates a Worm Which, in turn,operates a Worm Wheel yin the casing 69. The Worm Wheel operates a shaft70 which is connected through a coupling 71 to a shaft 72 which operatesa pair of bevel gears in the casing 73. The bevel gears in the casing 73drive the vertical shaft 74 upon which the driving pinion 50 is secured.The parts of the coupling 71 are adapted to be disconnected so that onlythe drive pinion and bevel gears of the spare or idle set Will beoperated during the operation of the table. lVhile We have shown thedrive units mounted upon integral bases, the various elements of thedrive units may be mounted upon separate bases or grouped upon aplurality of bases as desired.
